Non-woven fabric is a type of non-woven material. It is a new type of fiber product with a soft, breathable, and planar structure, formed directly from polymer chips, short fibers, or filaments through various web-forming methods and consolidation technologies. Compared to traditional plastic bags, non-woven bags offer several advantages: they are inexpensive, environmentally friendly, practical, widely applicable, and offer prominent advertising space. They are suitable for various business activities and exhibitions, making them ideal promotional gifts for businesses and institutions. The raw material for non-woven bags is polypropylene, while the raw material for plastic bags is polyethylene. Although the two substances have similar names, their chemical structures are quite different. Polyethylene has a highly stable chemical molecular structure, making it extremely difficult to degrade; therefore, plastic bags take 300 years to decompose completely. Polypropylene, on the other hand, has a less robust chemical structure, and its molecular chains break easily, allowing for effective degradation and entry into the next stage of the environmental cycle in a non-toxic form. A non-woven bag can completely decompose within 90 days.
Non-woven fabric is a product that resembles cloth but is not cloth without a weaving process; it is also called non-woven material. Because it is made simply by orienting or randomly arranging short or long textile fibers to form a web structure, and then reinforcing it using mechanical, thermal, or chemical methods. Most non-woven bags are made of spunbond non-woven fabric.
Simply put, non-woven fabric is not made by interlacing or weaving individual yarns together, but by directly bonding the fibers together using physical methods. Therefore, when you check the adhesive in your clothes, you will find that you cannot pull out individual threads. Non-woven fabric breaks through the traditional textile principles and has the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple raw material sources.
Laminated non-woven bags are made using a casting process, resulting in a strong composite. During the lamination process, no adhesive is used, resulting in a soft feel, no plastic-like texture, and no skin irritation. They are suitable for making disposable medical sheets, bed sheets, surgical gowns, isolation gowns, protective clothing, shoe covers, and other hygiene and protective products. Bags made from this type of fabric are called laminated non-woven bags.
